Answer 1

combine the x's so you have 3x+2y+8

Answer 2

3x+2y+8

Answer 3

think of each variable as a different kind of fruit. so lets say "x" is apples and "y" is orange. then all you need to do is group each type of fruit.

Answer 4

so the apples you have are 5 and -2, giving you 3 apples altogether
oranges are just 2
so you end up with
3x+2y+8
